perf tools: Add --debug optionto set debug variable
Adding --debug option as a way to setup debug variables. Starting with
support for verbose, more will come.
It's possible to use it now with report command:
$ perf --debug verbose ...
$ perf --debug verbose=2 ...
I'll need this support to add separated debug variable for ordered
events change in order to separate debug output out of standard verbose
stream.
